The OS provides no user-space hook for a process kill, but the activity onStop fires on every 'going away' transition the framework still controls: entering recents (the swipe-wipe path), app switch, and home. Recents-wipe then kills the process right after onStop returns, so that moment is the last reliable flush. - Logic.FlushSession (any goroutine, buffered, non-blocking) -> flushSessionSave on the owner: persist the snapshot now, bypassing the rate limit (still honoring the restore-pending suppression). saveSessionIfChanged's persist tail is deduplicated into writeSession. - JNI: GioActivity.onStop (patched into the smali by the build scripts, in sync) now calls the static native padFlushSession, which maps to the pad_flush_session cgo export. Verified on emulator: the flush fires on home/app-switch and when the app is backgrounded into recents before a kill; a state change made inside the 250ms rate window and then backed out of the app persists the latest position. A hard kill while foregrounded (force-stop, memory pressure) still has no hook — the immediate edit saves plus the 250ms rate window bound that loss.
